ReflectionProbe

Inherits: VisualInstance < Spatial < Node < Object

Captures its surroundings to create reflections.

Description

Captures its surroundings as a cubemap, and stores versions of it with increasing levels of blur to simulate different material roughnesses.

The ReflectionProbe is used to create high-quality reflections at the cost of performance. It can be combined with GIProbes and Screen Space Reflections to achieve high quality reflections. ReflectionProbes render all objects within their cull_mask, so updating them can be quite expensive. It is best to update them once with the important static objects and then leave them.

Enumerations

enum UpdateMode:

  • UPDATE_ONCE = 0 --- Update the probe once on the next frame. The corresponding radiance map will be generated over the following six frames. This is slower to update than UPDATE_ALWAYS but can result in higher quality reflections.
  • UPDATE_ALWAYS = 1 --- Update the probe every frame. This is needed when you want to capture dynamic objects. However, it results in an increased render time. Use UPDATE_ONCE whenever possible.

Property Descriptions

  • bool box_projection
Default false
Setter set_enable_box_projection(value)
Getter is_box_projection_enabled()

If true, enables box projection. This makes reflections look more correct in rectangle-shaped rooms by offsetting the reflection center depending on the camera's location.


  • int cull_mask
Default 1048575
Setter set_cull_mask(value)
Getter get_cull_mask()

Sets the cull mask which determines what objects are drawn by this probe. Every VisualInstance with a layer included in this cull mask will be rendered by the probe. It is best to only include large objects which are likely to take up a lot of space in the reflection in order to save on rendering cost.


  • bool enable_shadows
Default false
Setter set_enable_shadows(value)
Getter are_shadows_enabled()

If true, computes shadows in the reflection probe. This makes the reflection probe slower to render; you may want to disable this if using the UPDATE_ALWAYS update_mode.


Default Vector3( 1, 1, 1 )
Setter set_extents(value)
Getter get_extents()

The size of the reflection probe. The larger the extents the more space covered by the probe which will lower the perceived resolution. It is best to keep the extents only as large as you need them.


Default 1.0
Setter set_intensity(value)
Getter get_intensity()

Defines the reflection intensity. Intensity modulates the strength of the reflection.


  • Color interior_ambient_color
Default Color( 0, 0, 0, 1 )
Setter set_interior_ambient(value)
Getter get_interior_ambient()

Sets the ambient light color to be used when this probe is set to interior_enable.


  • float interior_ambient_contrib
Default 0.0
Setter set_interior_ambient_probe_contribution(value)
Getter get_interior_ambient_probe_contribution()

Sets the contribution value for how much the reflection affects the ambient light for this reflection probe when set to interior_enable. Useful so that ambient light matches the color of the room.


  • float interior_ambient_energy
Default 1.0
Setter set_interior_ambient_energy(value)
Getter get_interior_ambient_energy()

Sets the energy multiplier for this reflection probe's ambient light contribution when set to interior_enable.


  • bool interior_enable
Default false
Setter set_as_interior(value)
Getter is_set_as_interior()

If true, reflections will ignore sky contribution. Ambient lighting is then controlled by the interior_ambient_* properties.


Default 0.0
Setter set_max_distance(value)
Getter get_max_distance()

Sets the max distance away from the probe an object can be before it is culled.


Default Vector3( 0, 0, 0 )
Setter set_origin_offset(value)
Getter get_origin_offset()

Sets the origin offset to be used when this reflection probe is in box project mode.


Default 0
Setter set_update_mode(value)
Getter get_update_mode()

Sets how frequently the probe is updated. Can be UPDATE_ONCE or UPDATE_ALWAYS.
